<h1>nghttpx - HOW-TO<a class="headerlink" href="#nghttpx-how-to" title="Permalink to this headline">¶</a></h1>
|
||
|
|
<p>nghttpx is a proxy translating protocols between HTTP/2 and other
|
||
|
|
protocols (e.g., HTTP/1, SPDY). It operates in several modes and each
|
||
|
|
mode may require additional programs to work with. This article
|
||
|
|
describes each operation mode and explains the intended use-cases. It
|
||
|
|
also covers some useful options later.</p>
|
||
|
|
<div class="section" id="default-mode">
|
||
|
|
<h2>Default mode<a class="headerlink" href="#default-mode" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>If nghttpx is invoked without any <tt class="docutils literal"><span class="pre">-s</span></tt>, <tt class="docutils literal"><span class="pre">-p</span></tt> and <tt class="docutils literal"><span class="pre">--client</span></tt>, it
|
||
|
|
operates in default mode. In this mode, nghttpx frontend listens for
|
||
|
|
HTTP/2 requests and translates them to HTTP/1 requests. Thus it works
|
||
|
|
as reverse proxy (gateway) for HTTP/2 clients to HTTP/1 web server.
|
||
|
|
HTTP/1 requests are also supported in frontend as a fallback. If
|
||
|
|
nghttpx is linked with spdylay library and frontend connection is
|
||
|
|
SSL/TLS, the frontend also supports SPDY protocol.</p>
|
||
|
|
<p>By default, this mode’s frontend connection is encrypted using
|
||
|
|
SSL/TLS. So server’s private key and certificate must be supplied to
|
||
|
|
the command line (or through configuration file). In this case, the
|
||
|
|
fontend protocol selection will is done via ALPN or NPN.</p>
|
||
|
|
<p>With <tt class="docutils literal"><span class="pre">--frontend-no-tls</span></tt> option, user can turn off SSL/TLS in
|
||
|
|
frontend connection. In this case, SPDY protocol is not available
|
||
|
|
even if spdylay library is liked to nghttpx. HTTP/2 and HTTP/1 are
|
||
|
|
available on the frontend and a HTTP/1 connection can be upgraded to
|
||
|
|
HTTP/2 using HTTP Upgrade. Starting HTTP/2 connection by sending
|
||
|
|
HTTP/2 connection preface is also supported.</p>
|
||
|
|
<p>The backend is supposed to be HTTP/1 Web server. For example, to make
|
||
|
|
nghttpx listen to encrypted HTTP/2 requests at port 8443, and a
|
||
|
|
backend HTTP/1 web server is configured to listen to HTTP/1 request at
|
||
|
|
port 8080 in the same host, run nghttpx command-line like this:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ nghttpx -f0.0.0.0,8443 -b127.0.0.1,8080 /path/to/server.key /path/to/server.crt
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<p>Then HTTP/2 enabled client can access to the nghttpx in HTTP/2. For
|
||
|
|
example, you can send GET request to the server using nghttp:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ nghttp -nv https://localhost:8443/
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
</div>
|
||
|
|
<div class="section" id="http-2-proxy-mode">
|
||
|
|
<h2>HTTP/2 proxy mode<a class="headerlink" href="#http-2-proxy-mode" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>If nghttpx is invoked with <tt class="docutils literal"><span class="pre">-s</span></tt> option, it operates in HTTP/2 proxy
|
||
|
|
mode. The supported protocols in frontend and backend connections are
|
||
|
|
the same in <a class="reference internal" href="#default-mode">default mode</a>. The difference is that this mode acts like
|
||
|
|
forward proxy and assumes the backend is HTTP/1 proxy server (e.g.,
|
||
|
|
squid). So HTTP/1 request must include absolute URI in request line.</p>
|
||
|
|
<p>By default, frontend connection is encrypted, this mode is also called
|
||
|
|
secure proxy. If nghttpx is linked with spdylay, it supports SPDY
|
||
|
|
protocols and it works as so called SPDY proxy.</p>
|
||
|
|
<p>With <tt class="docutils literal"><span class="pre">--frontend-no-tls</span></tt> option, SSL/TLS is turned off in frontend
|
||
|
|
connection, so the connection gets insecure.</p>
|
||
|
|
<p>The backend must be HTTP/1 proxy server. nghttpx only supports 1
|
||
|
|
backend server address. It translates incoming requests to HTTP/1
|
||
|
|
request to backend server. The backend server performs real proxy
|
||
|
|
work for each request, for example, dispatching requests to the origin
|
||
|
|
server and caching contents.</p>
|
||
|
|
<p>For example, to make nghttpx listen to encrypted HTTP/2 requests at
|
||
|
|
port 8443, and a backend HTTP/1 proxy server is configured to listen
|
||
|
|
to HTTP/1 request at port 3128 in the same host, run nghttpx
|
||
|
|
command-line like this:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ nghttpx -s -f0.0.0.0,8443 -b127.0.0.1,3128 /path/to/server.key /path/to/server.crt
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<p>At the time of this writing, there is no known HTTP/2 client which
|
||
|
|
supports HTTP/2 proxy in this fashion. You can use Google Chrome to
|
||
|
|
use this as secure (SPDY) proxy to test it out, though it does not use
|
||
|
|
HTTP/2 at all.</p>
|
||
|
|
<p>The one way to configure Google Chrome to use secure proxy is create
|
||
|
|
proxy.pac script like this:</p>
|
||
|
|
<div class="highlight-javascript"><div class="highlight"><pre><span class="kd">function</span> <span class="nx">FindProxyForURL</span><span class="p">(</span><span class="nx">url</span><span class="p">,</span> <span class="nx">host</span><span class="p">)</span> <span class="p">{</span>
|
||
|
|
<span class="k">return</span> <span class="s2">"HTTPS SERVERADDR:PORT"</span><span class="p">;</span>
|
||
|
|
<span class="p">}</span>
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<p><tt class="docutils literal"><span class="pre">SERVERADDR</span></tt> and <tt class="docutils literal"><span class="pre">PORT</span></tt> is the hostname/address and port of the
|
||
|
|
machine nghttpx is running. Please note that Google Chrome requires
|
||
|
|
valid certificate for secure proxy.</p>
|
||
|
|
<p>Then run Google Chrome with the following arguments:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ google-chrome --proxy-pac-url=file:///path/to/proxy.pac --use-npn
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||

</div>

||
|
|
<div class="section" id="client-mode">
|
||
|
|
<h2>Client mode<a class="headerlink" href="#client-mode" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>If nghttpx is invoked with <tt class="docutils literal"><span class="pre">--client</span></tt> option, it operates in client
|
||
|
|
mode. In this mode, nghttpx listens for plain, unencrypted HTTP/2 and
|
||
|
|
HTTP/1 requests and translates them to encrypted HTTP/2 requests to
|
||
|
|
the backend. User cannot enable SSL/TLS in frontend connection.</p>
|
||
|
|
<p>HTTP/1 frontend connection can be upgraded to HTTP/2 using HTTP
|
||
|
|
Upgrade. To disable SSL/TLS in backend connection, use
|
||
|
|
<tt class="docutils literal"><span class="pre">--backend-no-tls</span></tt> option.</p>
|
||
|
|
<p>The backend connection is created one per worker (thread).</p>
|
||
|
|
<p>The backend server is supporsed to be a HTTP/2 web server (e.g.,
|
||
|
|
nghttpd). The one use-case of this mode is utilize existing HTTP/1
|
||
|
|
clients to test HTTP/2 deployment. Suppose that HTTP/2 web server
|
||
|
|
listens to port 80 without encryption. Then run nghttpx as client
|
||
|
|
mode to access to that web server:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ nghttpx --client -f127.0.0.1,8080 -b127.0.0.1,80 --backend-no-tls
|
||
|
|
</pre></div>
|
||
|
|
</div>
|
||
|
|
<div class="admonition note">
|
||
|
|
<p class="first admonition-title">Note</p>

|
||
|
|
insecure.</p>
|
||
|
|
</div>
|
||
|
|
<p>Then you can use curl to access HTTP/2 server via nghttpx:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ curl http://localhost:8080/
|

<tt class="docutils literal"><span class="pre">--backend-no-tls</span></tt> option.</p>
|
||
|
|
<p>The backend connection is created one per worker (thread).</p>
|
||
|
|
<p>The backend server must be a HTTP/2 proxy. You can use nghttpx in
|
||
|
|
<a class="reference internal" href="#http-2-proxy-mode">HTTP/2 proxy mode</a> as backend server. The one use-case of this mode
|
||
|
|
is utilize existing HTTP/1 clients to test HTTP/2 connections between
|
||
|
|
2 proxies. The another use-case is use this mode to aggregate local
|
||
|
|
HTTP/1 connections to one HTTP/2 backend encrypted connection. This
|
||
|
|
makes HTTP/1 clients which does not support secure proxy can use
|
||
|
|
secure HTTP/2 proxy via nghttpx client mode.</p>
|
||
|
|
<p>Suppose that HTTP/2 proxy listens to port 8443, just like we saw in
|
||
|
|
<a class="reference internal" href="#http-2-proxy-mode">HTTP/2 proxy mode</a>. To run nghttpx in client proxy mode to access
|
||
|
|
that server, invoke nghttpx like this:</p>
|
||
|
|
<div class="highlight-c"><div class="highlight"><pre>$ nghttpx -p -f127.0.0.1,8080 -b127.0.0.1,8443

|
||

</div>
|

<p>Then you can use curl to issue HTTP request via HTTP/2 proxy:</p>

|
<div class="highlight-c"><div class="highlight"><pre>$ curl --http-proxy=http://localhost:8080 http://www.google.com/
|
||
|
|
</pre></div>
|
||
|
|
</div>
|

proxy.</p>

<h2>HTTP/2 bridge mode<a class="headerlink" href="#http-2-bridge-mode" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>If nghttpx is invoked with <tt class="docutils literal"><span class="pre">--http2-bridge</span></tt> option, it operates in
|
||
|
|
HTTP/2 bridge mode. The supported protocols in frontend and backend
|

|
|
connections are the same in <a class="reference internal" href="#default-mode">default mode</a>.</p>
|
||
|
|
<p>With <tt class="docutils literal"><span class="pre">--frontend-no-tls</span></tt> option, SSL/TLS is turned off in frontend
|
||
|
|
connection, so the connection gets insecure.</p>
|
||
|
|
<p>The backend server is supporsed to be a HTTP/2 web server or HTTP/2
|
||
|
|
proxy. Since HTTP/2 requests opaque between proxied and non-proxied
|
||
|
|
request, the backend server may be proxy or just web server depending
|
||
|
|
on the context of incoming requests.</p>
|
||
|
|
<p>The use-case of this mode is aggregate the incoming connections to one
|
||
|
|
HTTP/2 connection. One backend HTTP/2 connection is created per
|
||
|
|
worker (thread).</p>

<p>By default, nghttpx tries to read CA certificate from system. But

depending on the system you use, this may fail or is not supported.

To specify CA certificate manually, use <tt class="docutils literal"><span class="pre">--cacert</span></tt> option. The

<p>nghttpx supports transfer rate limiting on frontend connections. You
